Challenges for Vaccine Credentials

Solutions via Paper QR Credentials

Standards

Long wait for ‘common standard’ to emerge for issuance so that verification can become simple

No standards required for QR code in short term. Transfer complexity to free universal scanning apps that can read any QR vaxcred

Ecosystem

Integration complexity with external ecosystem of Blockchain, EHR, identity

Treat vaxcreds as one-way offline output with no linkage back to EHR/Blockchain for verification.

With no reverse linkage, no PII audit trail possible.

No additional user data collection required.

Biz Model

Companies pushing models with cloud services, pay-per-verification, exploit streaming data

Use offline-offline solution, nearly free to everyone. States can pay for app.

Equity

Govt insists equity, work without smartphones, no persona data for vulnerable population

Paper-first approach, selective disclosure with initials/year e.g. JD80 or hash (not full PII). VaxCred has no health or full name/DoB data.

Certificate = (message, signature(message))

For each sticker below (except passkey), the message is as follows

​

Badge = (dose_info, PII) = (Pfizer X3D421, Dose1, Jane Doe, 1/1/1980)

Status = (vaccinated = 0,1,2, PII) = (2, JD80)

​

Certificate = (message, signature(message))

For each sticker below (except passkey), the message is as follows

​

Coupon = (number, total, city, phase, (age, job, sick), PII) = (37, 5000, Springfield, 1B, Teacher, JD)

Badge = (dose_info, PII) = (Pfizer X3D421, Dose1, Jane Doe, 1/1/1980)

Status = (vaccinated = 0,1,2, PII) = (2, JD80)

​

Type 2: Eligibility coupon and vaccination credentials

​

For Vulnerable Population, no PII

Certificate = (message, signature(message))

For each sticker below (except passkey), the message is as follows

​

Coupon = (number, total, city, phase, (age, job, sick)) = (37, 5000, Springfield, 1B, Teacher, [JD])

Badge = (coupon, dose_info, hash(passkey)) = (h723w86, Pfizer X3D421, Dose1, sj2d8k8hy7j)

Status = (vaccinated = 0,1,2, hash(passkey)) = (2, sj2d8k8hy7j)

Passkey = (name, DoB, salt) = (Jane Doe, 01/01/1980, 1687216876123)

= hash: sj2d8k8hy7j

Type 3: Passkey hash for Vulnerable population, no PII upload
